Rudder randomly twitchy with Savage Cub

There are no joystick settings in windows that I can find. There is a Thrustmaster folder but it has no settings that can be changed to default.
I have thrown thousands and thousands of dollars at this simulator in order to get it to work at it’s best. -All I get is aggravation and huge bug infested downloads that take up what little flying time I have available.
Thanks for your attempt to help.
No need to reply, I’m not putting in another dime or minute of my time.
